The distance between the contact surfaces of the sponge bodies 6 and 8 is set to be smaller than the diameter of the seedling 41, and the separated seedling 41 is sandwiched between the sponge bodies 6 and 8 to be fed out. The pair of belts 5 and 7 are rotated by pulleys 11 and 12, and spur gears (not shown) having the same number of teeth are fitted and meshed with shafts 9 and 10 in a frame 19. Rotate at the same peripheral speed in opposite directions,
It rotates at a speed slightly faster than the outer peripheral speed of 1,2. In front of the rollers 1 and 2, there is provided a horizontal moving machine side 20 which reciprocates in a horizontal direction perpendicular to the conveying direction of the seedlings 41 of the pair of belts 5 and 7. Then, the group of aligned seedlings 40
And put the seedlings 41a, 41b, 41c, ... in the front row in the separation section.
... are supplied from the lateral direction. The lateral moving mechanism 20 includes a lateral moving mechanism frame 21 that is substantially rectangular in plan view.
A pair of seedling guides 22 is provided above and below the horizontal moving mechanism frame 21 at a slightly wider interval than the width of the aligned seedlings 40, and a horizontal moving mechanism 20 is provided below the horizontal moving mechanism frame 21. Provide two shafts 23 and 24 at the same height long in the movement direction,
The shafts 23 and 24 are fitted into 1 and move along them. The shaft 23 has a cylindrical cam (not shown) formed by a rice transplanter or the like in which a forward groove and a return groove are formed in an endless cross shape, and is engaged with a projection (not shown) provided on the lateral movement mechanism frame 21. As the shaft 23 rotates, the horizontal moving mechanism frame 21 reciprocates continuously in the horizontal direction. The moving speed is lower than the outer peripheral speed of the rollers 1 and 2, and in the embodiment, the moving speed is about 1/3. The lateral moving mechanism frame 21 of the lateral moving mechanism 20 has a pair of belts 5,
The vertical movement mechanism 30 that moves the seedling 41 in the vertical direction in the transport direction is provided. Then, the group of aligned seedlings 40 is placed on the vertical moving mechanism 30 and is sent out intermittently at the left and right moving ends of the horizontal moving mechanism 20 in the vertical direction.

A pulley 32 is provided on the side that is longer than the rollers 1 and 2 at the same height and is long in the moving direction, and a pulley 33 is also provided on the side closer to the rollers 1 and 2. Between the two pulleys 32 and 33, a belt 31 having a width slightly smaller than the width of the lateral movement mechanism frame 21 is stretched.
The rotation of the shaft 24 is transmitted to the pulley 32 even when the lateral movement mechanism frame 21 moves in the lateral direction.
The shaft 24 rotates so as to vertically feed the seedling row of the aligned seedlings 40 in the direction of the rollers 1 and 2 at the moving end of. Next, the operation will be described. The horizontal moving mechanism 20 of the separation device is set at a predetermined moving end, and the group of aligned seedlings 40 is placed on a belt 31 as a vertical moving mechanism 30 on the horizontal moving mechanism 20, and the front end of the group of aligned seedlings 40 is on the roller 2 side. It is sent to a position in contact with the seedling regulator 14. At this time, the front end of the roller 1 as a rotating body is located at substantially the same position as the front end of the second row of the group of aligned seedlings 40.
Is located away from the front end of the front row of the aligned seedling group 40. When the shafts 3, 4 and the shafts 9, 10, and the shaft 23 rotate by appropriate means, the rollers 1, 2 and the pair of belts 5, 7 rotate, and the lateral movement mechanism frame 21 moves in the lateral direction. As a result, the seedling to be separated in the front row of the aligned seedling group 40
The front end of the roller 1 as a rotating body contacts the side surface of 41a and rotates. At this time, the rotation direction of the roller 1 is such that the side contacting the side surface of the separated seedling 41a of the roller 1 is the aligned seedling group 40.
Rotating in the direction opposite to the moving direction of the
Since the moving speed is higher than the moving speed of the seedlings 41a to be separated, a force in the same plane direction as the surface of the aligned seedling group 40 is applied from the roller 1 to the separated seedlings 41a, and the separated seedlings 41a try to rotate in that plane, Next, the seedling container 4 with the seedling 41b to be separated and the following seedling row
(2) The mutual connection is peeled off without difficulty from its end, and separated without forming a row of seedlings. The disconnected seedlings 41 are sandwiched and held between the roller 1 and the guide body 14a opposed thereto, and are transported and rolled out while being rolled by the rotation of the roller 1 to form an aligned seedling group.
Forcibly pulled further away from 40. The seedling 41 that has passed through the guide body 14a is sandwiched between the rollers 1 and 2 and is fed out, and is immediately held between the sponge bodies 6 and 8 of the pair of belts 5 and 7 and is sent out further.
For this reason, even if there is a leaf entanglement or root entanglement between the separated seedling 41 and the aligned seedling group 40, they are fed out while maintaining the separated position sufficiently far enough to separate them, and the separation is assured. Become. In addition, the aligned seedling group 40 is a seedling separated by the lateral movement mechanism 20.
Because it moves along the column direction of 41a, 41b, 41c, ...
The front row of the aligned seedling group 40 is sequentially separated into individual seedlings 41, and the separated seedlings 41 are taken out one by one from the belts 5, 7. All the separation of the front row of the aligned seedling group 40 is completed, and the horizontal movement mechanism 20
When the robot reaches the moving end, as shown in FIG.
The aligned seedling group 40 is sent out by one row in the vertical direction by one row of seedlings, and at the same time, the rollers 1 and 2 advance and retreat to change the role of the rotating body.
a and the guide body 14a of the seedling regulating body 14 advances and retreats and changes the role of the guide body, and the lateral movement mechanism 20 arranges the seedling group arranged in the opposite direction as before.
The next row is started by moving 40 horizontally. In FIG. 1 and FIG. 2, the reference numerals of the parts whose roles have been changed are exchanged according to the roles. In the above embodiment, the seedling growing container 42 made of a paper cylinder is shown as the aligned seedling group 40.However, even if the seedling growing medium itself is made of an inorganic fiber or a polymer compound forming the seedling growing container, the individual seedlings 41 What is necessary is just what is connected neatly so that separable. Although the sponge roller 1 is shown as a rotating body, the rotating body may be in the form of a belt. In this case, leaf entanglement or root entanglement occurs between the separated seedling 41 and the aligned seedling group 40. Even if there is, it can be extended far enough to separate it. In addition, although a sponge body is shown because a paper tube seedling is illustrated, an elastic body such as rubber having a large number of protrusions provided on a rigid roller such as a synthetic resin may be used. Also, the example has been described in which the rotating body is moved forward and backward at the moving end of the horizontal moving mechanism 20 to alternately perform its role and continuously separates. You can change it with
May be prepared, and may be sequentially replaced to be separated continuously. Further, the example in which the aligned seedling group 40 is intermittently fed by the vertical moving mechanism 30 at the moving end of the horizontal moving mechanism 20 has been described, but the aligned body of seedling group 40 is continuously fed to rotate the rotating body 1 and the seedling regulating bodies 13 and 14. It may be moved correspondingly. In addition, although the example in which the aligned seedling group 40 is moved in the horizontal direction and separated from the standing state by the rotating body 1 is shown, the aligned seedling group 40 may be in an oblique state or an inverted state, and the moving direction of the aligned seedling group 40 is also separated. The direction is not limited to the horizontal direction as long as it is in the seedling row direction. For example, the seedling row may be moved in the vertical direction and separated. In addition, although the guide 14a is provided at one end of the seedling regulating body 14 to move forward and backward together, the guide 14a may be provided independently and does not necessarily need to move forward and backward. Also, an example was shown in which the seedling 41 that was fed out between the rollers 1 and 2 was fed out while being sandwiched between a pair of belts 5 and 7.
Seedling 41 that was fed out between roller 1 and guide 14a
May be dropped on a gutter or the like as it is, or may be planted after being inverted, placed on a belt, transported and aligned.
